Kukonza shaft yozungulira mu chogwirira chakale chomwe chimagwiritsidwa ntchito popanga zinthu za latex zoviikidwa momwe shaft imalumikizidwa ku unit yolumikizira ku unyolo wotumizira ndi thupi lozungulira lomwe limasunga lakale. Chogwirira chakale chimaphatikizapo thupi lozungulira lomwe lili ndi gawo lapakati lolowera (15) kuti ligwirizane ndi lakale; shaft yozungulira yooneka ngati d yoyikidwa ndikukhazikika ku thupi lozungulira; njira yotsekera yogwirira ndikutseka lakale. Thupi lozungulira la chogwirira chakale lili ndi chitsogozo chakale chomwe chili pakati pa gawo lolowera ndipo limatha kulumikizana bwino ndi kutsegula pakamwa la lakale. shaft yokhala ndi gawo lozungulira looneka ngati d kumapeto amodzi yotetezedwa ndi njira yotsekera yomwe imakonzedwa bwino ku ngodya yoyenera ku chitsogozo chakale; malekezero ena a shaft amalumikizidwa ku unit yolumikizira yolumikizidwa ndi unyolo wotumizira. Njira yotsekera imatha kusunthidwa motsatira mzere wamba wa shaft ndi njira yotsekera ya seti ya chogwirira ndipo imayatsidwa ndi kasupe wa njira zotsekera kuti zisunge ndikutseka lakale mwamphamvu.

"Makonzedwe ndi njira yosonkhanitsira zogwirira zakale" akuwonetsa dongosolo ndi njira yosonkhanitsira zogwirira zakale kuti zisinthe njira yachizolowezi yogwiritsira ntchito chogwirira chimodzi kuti ziwonjezere kuchuluka ndi kupanga bwino popanga magolovesi. Njira yosonkhanitsira zogwirira zakale popanga magolovesi a buku lomwe lawululidwa ikuphatikiza pini yolumikizidwa kumapeto kwa shaft iliyonse yomwe imachokera ku unyolo womwewo; ma hinge awiri olumikizidwa ku pini iliyonse amakhala ndi chogwirira, zomwe zikutanthauza kuti zogwirira ziwiri zakale zimagawana chowonjezera chimodzi, pomwe ma hinge awiri omwe ali pa chowonjezera chomwecho cha shaft amakhala ndi chimodzi pamwamba pa chinzake panthawi yopanga magolovesi ndipo awiriawiri omwe ali kumapeto kwa chowonjezera chilichonse amalekanitsidwa ndi chimodzi mwa zogwirira zakale zomwe zapendekeka ndi madigiri 90 kutali ndi malo ake oyamba panthawi yosindikiza ndi kuchotsa magolovesi. Komabe, mphamvu yochotsera ya dongosolo lomwe lili pamwambapa la zogwirira zakale silikukwanira pamlingo womwe mukufuna. Kuphatikiza apo, ndi dongosolo lomwe lili pamwambapa pali mwayi woti magolovesi adutse panthawi yochotsa, zomwe zimachepetsanso mphamvu ya njira yopangira magolovesi.
